The ZXing plugin provide an easy way to embed 1D/2D barcode into your document.

Example

You will need to define a size (width/height) for your object:

<html>
  <body>
    <h1>Default barcode: qrcode</h1>
    <object type="image/barcode" style="width:60px;height:60px;" value="hello world"></object>
    <h1>Select barcode type:</h1>
    <object type="image/barcode" style="width:50px;height:20px;" value="123" format="CODE_39"></object>
    <h1>Encode hint</h1>
    <object type="image/barcode" style="width:100px;height:40px;border:1px solid red;" format="DATA_MATRIX" value="hello world">
      <encode-hint name="DATA_MATRIX_SHAPE" value="FORCE_RECTANGLE"></encode-hint>
    </object>
  </body>
</html>

            builder.withUri("barcode.html");
            builder.useFastMode();
            builder.toStream(os);
            
            DefaultObjectDrawerFactory factory = new DefaultObjectDrawerFactory();
            factory.registerDrawer("image/barcode", new ZXingObjectDrawer());
            builder.useObjectDrawerFactory(factory);

            builder.run();
